Conventional HEPA filter
HEPA filter is made of dense fiberglass to trap particles, which means that less clean air get through the filter.
Less clean air
Large volume air is forced to get through a dense HEPA filter, requires higher fan speed, which will generate higher noise.
In order to get more clean air, HEPA filter requires the motor to run at a higher speed, which causes higher energy consumption.
Higher energy consumption
Xiaomi's High Efficiency Filter
Xiaomi's filter integrated melt-blown PP fibers with electrostatics technology equipped with bigger fibers space, which enables a large volume clean air to get through the filter.
More clean air
Less dense fibers filter is easy to have the air passed even in a high speed, which results in much lower noise.
Thanks to a less dense fibers filter, Xiaomi's filter consumes less energy to achieve the same volume clean air.
Lower energy consumption
*The filter media performance is tested by China Testing & Inspection Institute for Household Electric Appliances (Report Number: WCv-21-40115). Due to the technical specifications of the filter media, the test environment and parameters may differ.
